Trouble Finding High Horse D8H 46A Turbo

Hello folks. The turbo bearings on my 46A have failed. Lots of smoke and intermittent power loss. Removed air cleaner to find fore and aft play and wobble on the turbine. The tractor has an early serial number and someone before me stuck a high horse engine in it so serial number on tractor won’t help me for sourcing a replacement. The turbo appears to be a Garrett make, model T1867 with customer (Cat) number 4N5645 and no Garrett part number on it. I have called a few places and scoured the internet for a match but nothing for 4N5645 that isn’t outrageously priced.

My question is, is there another cat part number that will work on my engine? There seems to be a few different ones online for D8H but I don’t know if they would fit. Thanks for any help folks.

Here's a link to several companies that have them for sale:

I've also seen on YouTube an outfit called Area Diesel Service that is very capable of rebuilding yours:

Thanks. I must’ve had fat fingers last night, the cat number is actually 4N5645 and nothing comes up in machinery trader when I put that in. I’ve seen the area diesel video for Dieael Creek. Would probably be crazy shipping from up here in Canada, but I was going to start calling turbo shops up here on Monday.

I can find 0R-5841 turbos which are a T1238 model that are for D8K…… Some google searches say for D8H as well, but I don’t know if that would be correct.

For shipping, you can just send ADS the cartridge comprising the central housing, the shaft, the impeller, and the turbine. That would save a bunch on weight and dimensions. Just be careful removing the two volutes
